Giving back has to do with the way I was brought up and the fact that I've traveled widely and seen terrible situations in the world. To sleep well at night, those of us who are in a position to help must address these situations. I'd get far greater satisfaction out of, say, walking into a hospital I'd built in South Africa than I would by sitting on a beach. I'm fortunate enough to be in a position to make a difference, and I don't want to waste that. I suspect I was also lucky to have parents who drove me from a young age.

If you can run one company, you can run another. Running companies are about inspiring and driving the best out of people.

I never went into business just to make money - but I found that if I have fun, the money will come. I often ask myself, is my work fun and does it make me happy? I believe that the answer to that is more important than fame or fortune. If it stops being fun, I ask why? If I can't fix it, I stop doing it.

To launch a business means successfully solving problems. Solving problems means listening.

I've had many challenges - every entrepreneur does - it's the nature of the beast.

You can create a business, choose a name, but unless people know about it you're not going to sell any products.

If you're hurt, lick your wounds and get up again. If you've given it your absolute best, it's time to move forward.
